Heisenberg's uncertainty principle, find uncertainty in position
1. The problem statement, all variables and given/known data
Using Heisenberg's uncertainty principle, calculate the uncertainty in the position of a proton moving at a speed of (5.00±0.01) x 10^4 m/s.
2. Relevant equations
3. The attempt at a solution
x[itex]\geq[/itex] (6.626*10^-34)/(4pi(1.6726*10^-24)(5±0.01 * 10^4)
I get how to solve it, I just don't really understand what to do with the ±0.01. I'm assuming it's in meters, so I have to do 0.01/5 and then multiply that by 5*10^4, but I'm supposed to be getting 3*10^-10
Thanks in advance (:
